Abstract: In recent years, global food safety issues have been increasingly prevalent, posing threats to people's health and lives. Traditional food traceability systems face significant challenges due to centralised storage, data silos, and the potential for information tampering. This article proposes an improved RAFT consensus algorithm for the first time, applied to trace the production process of food based on private chains. Subsequently, an enhanced PBFT consensus algorithm is introduced for tracing the distribution process of food based on consortium chains. Finally, a reliable dual-chain food quality and safety traceability system based on the Ethereum blockchain platform is presented. This system effectively addresses data reliability issues on the chain by introducing a reliability measurement evaluation module. Moreover, the application of aggregated signature technology enhances the performance of the traceability system, ensuring the authenticity, reliability, and tamper resistance of traceability information. This innovation not only strengthens the privacy protection and data security of food quality and safety tracking but also helps maintain the commercial interests of all parties involved.

Keywords: food traceability; blockchain; cross-agency traceability system.
